Your answer is sooo close!!! But I think it is precisely about the same. :)
4AI(s) + 302(g) = 2 AI203(s)
O1Fl2
1. Assume an 100g sample, so the percentage will stay the same
2. Covert each element into their molar mass
29.6/16.00=1.8 mols of O
70.4/19.00=3.7 mols of Fl
3. Divide both by the smallest value of mol
1.8/1.8=1 O
3.7/1.8=2 Fl
4. Write the empirical formula:
O1Fl2
Answer:
The kilogram is the standard unit of mass.
C6H12O6
That is the molecular formula of glucose
